I made an FE8 version. FE8 uses fewer samples and also a lot of them are shorter than the FE7 versions, not sure why that is. I found a couple of leftover FE7 samples that weren’t referenced by any instrument map, there’s probably more out there but I didn’t bother looking.

Edit: Fixed some of the Attack/Decay/etc values, caught error in instrument list. Also created the FE8 Drums fix patch which fills in the missing notes from 35-81 (except 71-72 Short and Long Whistle). This fixes the boops as long as you use the General MIDI drum notes.
